Answer by mareeclara
The gene for Haemophilia is carried on the X chromosome. Firstly here are the genotypes and phenotypes for the condition where C is normal and c is the defective allele (note the C’s are superscript):

XCXC = normal female
XCXc = carrier female
XcXc = affected female

XCY- normal male
XcY – affected male

XCXCY = Unknown Affected Fe-male autisum. Idk just guessing :P
